Possible engine-control role

Engine control software manages functions such as fuel delivery, ignition timing and emissions control using sensor readings and operating conditions. These functions affect how the engine starts, responds to the accelerator and operates as the vehicle is driven. The identifier alone does not establish what this particular calibration changes.

The filename suffix - (2) does not identify a named stock or modified variant. The catalog entry does not establish a specific vehicle application or compatibility.
